Sap Sipper

Description

This Pokémon is herbivorous, and its swift metabolism allows it to quickly extract energy from the plants it eats, while its adaptations to consuming plantlife have left it immune to their best attempts at hindering it. Any Grass-type attack used against this Pokémon is no more than fodder for it to consume and convert to power for its future attacks. A Pokémon with this ability is completely unaffected by Grass-type attacks, and if struck by one, its Attack will rise by one level.
